Make compatible with newlib

[rickgaiser]

This is the PR for making OPL compatible with newlib.

ps2toolchain, ps2sdk, ps2sdk-ports and gsKit have already been updated to newlib. Please update your entire toolchain before testing this.

@rickgaiser, thank you very much for the work, you can provide a test build please
compiled with all this updates for we can test it?

Best regards.

[rickgaiser]

No, sorry.

You'll have to update your toolchain anyway. If you have your toolchain updated you can test this PR with:

# Add remote repository
git remote add rickgaiser https://github.com/rickgaiser/Open-PS2-Loader
git fetch rickgaiser

# Checkout PR and test it
git checkout rickgaiser/for-ifcaro-newlib -b newlib-pr-test
make clean run

# Go back to ifcaro/master branch, and cleanup newly created PR test branch
git checkout master
git branch -d newlib-pr-test

Built everything from scratch (toolchain, sdk, sdk-ports, gskit).. newlib port of OPL is working great, didn’t have any issues during my tests.. BMP COVs are now working without problems also. Great work!

[rickgaiser]

I've added the bugfixes from my stable master-ps2max branch. One of them fixes the notification issue, as reported on psx-place.

[rickgaiser]

Thank you for merging, now we can move on. The exit issue should still be present, so I'll make a separate issue for it.

Also note that there's a recent change in gsKit by @KrahJohlito that fixes a bmp issue. So please update everything again before releasing a build.

@rickgaiser, thank you very much, i updated all, made the merge of newlib, and compiled
the OPL just this yesterday night, all this night.

And i saw now in the gsKit repository that the bmp fix made by @KrahJohlito was
made 3 days ago, so i already have everything updated right?

Best regards.

[rickgaiser]

Yes, if you've updated everything last night then you should have the latests of everything.

[ElPatas1]

@rickgaiser, yes, thank you very much.

Best regards.
